WARWICK, R.I. (WPRI) — A lockdown at several Warwick schools Friday morning has been lifted and all students are safe, Superintendent Dr. Philip Thornton confirms.

In a letter to parents, school officials said the lockdown was put in place out of an abundance of caution during a police investigation at Toll Gate High School.

According to Dr. Thornton, the investigation stemmed from a rumor that there was a possible weapon at the school.

City police later said it also involved a suspicious statement made within the school facility. After concluding their investigation, police said it was determined there was no safety risk to students or faculty.

Nearby Winman Junior High School, Warwick Career and Technical Center and Drum Rock Early Childhood Center were also locked down as a precaution.

Thornton said the school day resumed as normal after the lockdown was lifted.

Below is the full letter sent to parents Friday morning.

This is to notify you that Toll Gate High School is in a lockdown and all students are safe.

Upon the completion of the police investigation, the lockdown will be lifted and you will be notified.”
